BACKGROUND OF THE INVENTION An object of the present invention is toprovide an apparatus and a process for bleaching, dyeing and sizing andotherwise finishing warps and arranging them in a predetermined colorarrangement on bobbins for use in a subsequent weaving operation.

Another object of the present invention is to provide an apparatus and aprocess for mechanically collecting and supporting unit color arrangedwarp winding bobbins one after another. Another object of the presentinvention is to provide a simple and inexpensive apparatus and processfor consecutively performing the most difficult warping operation in aweaving process.

In accordance with this invention, therefore, it is not necessary tomanually arrange individual colored warp bobbins which have beenseparately dyed and otherwise finished on a creel stand. Thus, thisinvention saves a considerable amount of time and trained labor. Inaddition, unit color arranged warp winding bobbins are collected andsupported mechanically on a frame. Here again, this invention saves aconsiderable amount of time and trained labor.

In weaving a striped fabric consisting of a repitition of a unit colorarrangement, individual warp cheeses have heretofore been hank reeled,and separately bleached, dyed and otherwise liquid treated to be therequired colors. After sizing, such warps in hank form have been driedin a drying apparatus for a certain period of time, and separatelyrewound according to color. Next, as many as several thousands ofindividual cheeses have been arranged in a predetermined color on acreel stand by trained laborers.

Each colored warp so obtained has been wound on a warping machine, andthen on a beam. These processes have constituted warping operationssuitable for weaving a cloth. Such warping operations have been regardedas difiicult and time consuming operations and are the very reason whyweaving multi-colored patterns is regarded as very difficult.

In accordance with this invention, however, a unit group of coloredwarps arranged as desired is obtained during a consecutive liquidtreatment of warps without the necessity of hank reeling. And anultimate warp is obtained by collecting and supporting a plurality ofsaid unit groups in a predetermined arrangement. Thus, the process ofthis invention is quite consecutive, and the complicated and difficultcreel stand system is eliminated. In addition, the operations of bankingand rewinding may be markedly simplified. Thus, operations are sosimplified that the number of warp breaks is greatly reduced. Thus, itmay be said that this invention has made a great improvement in thepreparation of threads to be used as warps in subsequent weavingoperations.

Now the present invention will be described in detail with reference tothe accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagrammatic sideelevational view of the warping system embodying the present invention;

FIG. 2 is a sectional view of a bobbin for winding a unit color arrangedwarp;

' FIG. 3 is a perspective view of a skeweredand wound bobbin; I

FIG. 4 is a perspective view of a group of warp wind ing bobbinssupported by a supporting frame;

FIGS. 5, 6 and 7 are respectively cross-sectional views of thebleaching, dyeing and sizing baths shown in FIG. 1;

FIG. 8 is an enlarged view of the bleaching bath; and FIG. 9 is a detailview of the reel shown in FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION The numeral 1 designates ten warpcheeses which are rotatably supported in parallel. The term warp threadas employed herein refers to a single strand of one thread or aplurality of threads spun together in any conventional manner. Thenumeral 2 designates a bleaching bath. The numeral 3 designates a guideroll for the bleaching bath. The bleaching bath is designed to treat tenwarp threads at a time. As shown in FIG. 5, a bleaching liquid 2' isprovided in the bleaching bath 2, and the single roll 3 extends acrossthe length of bath 2. Roll 3 is rotatably attached with its lower partimmersed in bleaching liquid 2'. Thus, the surface of roll 3 always hasthe bleaching liquid applied thereto. Ten yarns 1' drawn from the tencheeses 1 contact the surface of roll 3 at predetermined distances fromone another and run parallel with one another. Here the bleaching liquidon the surface of roll 3 is applied to the ten yams 1, which are therebybleached.

The threads are drawn over roll 3 as shown in FIG. 8. The container 30of bleaching bath 2 is. shaped as shown. A dyeing roll 3 has its lowerpart 3' immersed in the liquid bleach filling container 30. The side 3'of the dyeing roll 3 projects laterally further than the extreme portion30 of the container 30. Liquid bleach is supplied through entrance 31and exits from outlet 32. The quantity of bleach solution is thuscontrolled so that it is always at the same level. The threads 1 passover guide roll 33 and are brought into contact with the side 3" of thedyeing roll 3, and advance in a curved direction without being touchedby the extreme portion 30 of the container 30 before they are led to aguide roll 34. The threads are bleached when brought into contact withthe side 3" of the dyeing roll 3 which is rotating in the direction ofthe arrow.

The dyeing and sizing baths have the same structure as the abovedescribed bleaching bath, and accordingly will not be described infurther detail.

The numeral 4 designates a dyeing bath and the numeral 5 designates adyeing roll, ten of which are provided side by side such that eachrespective bleached warp thread may be dyed with a predetermineddifferent color. As shown in FIG. 6, the dyeing bath 4 consists of tenbaths separated from one another by means of partitions 4', each ofwhich is placed between any two baths. Thus, there is no mixing of thedyeing liquid among the ten baths. Each dyeing liquid 5' in the tenbaths may be different from the other nine. Each separate dyeing bath isprovided with a rotatable dyeing roll 5. Thus, there are ten such dyeingrolls in all.

Each such dyeing roll 5 always has the lower part surfaces of ten dyeingrolls, and each of the yarns is dyed a different color.

The numeral 6 designates a sizing bath and the numeral 7 designates asizing roll, of which are provided side by side such that the color ofeach respective colored warp thread will not be blended. As shown inFIG. 7, the sizing bath 6 consists of ten baths separated from oneanother by means of partitions 6, each of which is placed between anytwo baths. Thus, there is no mixing of sizing liquid among the tenbaths. A sizing liquid 7 is contained in each separated sizing bathwhich are provided with individual rotatable sizing rolls 7, the lowerparts of which are always immersed in the sizing liquid 7. As each roll7 rotates its entire surface thereof always has the sizing liquid 7applied thereto.

Thus, the yarns dyed different colors in the dying bath move forwardwhile contactingthe surfaces of the 10 sizing rolls 7 and thereby absorbthe sizing liquid 7' from the surfaces of the sizing rolls. It is notnecessary, of course, that there should be ten kinds of sizing liquids.One kind of sizing liquid is satisfactory. But the colors of yarnsimmediately after dyeing may run womewhat into the sizing liquid. Ifthis phenomenon continues, the sizing liquid in the bath may be coloredwith respective different colors. Thus, the sizing bath 6 is dividedinto 10 separate baths to preventcolored sizing liquid from mixing. Inthe event that the bleaching liquid is acidic and the dyeing liquids arealkaline, or vice versa, it will be necessary to provide a conventionaldrying device between bleaching bath 2 and dyeing bath 4. However, ifthe bleaching liquid and dyeing liquids are both acidic or bothalkaline, then it is unnecessary to provide such a drying device.

Furthermore, since there are 10 separate sizing baths, there is no needto dry the dyed threads before they enter the separate sizing baths.

The numeral 8 designates a drying chamber provided with a timing reeldevice 9 which moves the 10 treated warp threads side by side andconsecutively dries them. The 10 colored yarns bleached, dyed and sizedin the preceding processes are arranged in a rank and are adjusted bymeans of a guide r. Then they run parallel and spaced from one anotherinto the timing reel device 9.

' In FIG. 9, 101 designates a driving shaft, 102 a ratchet wheel forrotating a main shaft 103, 104 an endless chain, and 105 a ratchet wheelfor the main shaft. The endless chain 104 moves the main shaft inresponse to rotation of driving shaft 101. 106 designates a frame forthe reel 9 fixedly provided near the ends of the main 90. A plurality ofpairs of screw gears 110 and 111 are positioned radially on frame 106with main shaft 103 as the center. A plurality of ratchet wheels 112 areprovided on the shafls supporting screw gears 111. A plurality ofratchet wheels 1 13 are positioned radially outwardly on frame 106 fromwheels 112. The number of ratchet wheels 112 is the same as that of theratchet wheels 1 13, and a plurality of endless chains 1 14 move theratchet wheels 112 and 113 in a correlated manner.

A plurality of ratchet wheels 115 are provided on the same shaftssupporting ratchet wheels 113. A plurality of ratchet wheels 116 arelongitudinally aligned with ratchet wheels 115 near the outercircumference of the lower part of the frame 106. The number of ratchetwheels 116 is the same as that of the ratchet wheels 1 15. A pluralityof endless chains 1 17 move the ratchet wheels 115 and 116 in acorrelated manner. All of the endless chains 117 are located in such-away as to form the outer cylindrical surface of the reel 9. By therotation of the main shaft of the reel, the yarns are wrapped on thecircumferential surface of reel 9. But what con stitutes this surface ofthe reel is not a static surface, but a number of chains always movingfrom the top to the bottom. Thus, each of the yarns which enter the reelmoves towards the lower portion thereof while being revolved round thereel. When the yarns approach the bottom of the reel, they advance to atraverse yarn guide 11 which is provided with 10 grooves therein (seeFIG. 2). Said traverse yarn guide 11 leads the yarns to a winding bobbin13 as shown in F IG.- 2. By the rotation of the drive roller 14 which isin contact with the outer circumference of the wound yarns 15 on thewinding bobbin 13, the 10 yarns of dif- I ferent colors are wound onbobbin-13 in an arranged cording to a prearranged order in such a way asto be freely movable. Such an arrangement provides a situation in which10 sets of 10 yarns of different colors, that is yarns, are arranged ina predetermined manner to form a skewered and wound bobbin 17.

A suitable or desirable number of skewered and wound bobbins 17 arearranged on a cylindrical frame 18. Frame 18 may be any suitable devicearranged to support the ends of bars 16 of the skewered and woundbobbins 18. In FIG. 4 there are shown eighteen bobbins 17 arrangedaround the periphery of frame 18. It is to be understood that frame 18may be adapted to contain any number of bobbins 18. A particularlyuseful arrangement would include fifty skewered and wound bobbins 17,thus providing 5,000 treated yarns to be used in subsequent weavingoperations. Thus, the arrangement shown in FIG. 4 provides a greatquantity of yarns 19 of various colors in a predetermined arrangementfor use in a subsequent weaving operation.

The apparatus and process for warping in accordance with this inventioneliminates the use for skilled labor required for a creel stand,eliminates a substantial part of heretofore frequent winding and similaroperations, and reduces the number of yarn breaks.

What is claimed is:

1. A process for preparing colored, wound warp yams for use in a weavingoperation, said process comprising the steps of withdrawing a pluralityof untreated warps from a plurality of warp bobbins; passing saidplurality of warps through a bleaching bath, thereby bleaching saidwarps; simultaneously passing each of said plurality of bleached warpsthrough a separate dyeing bath, each of said dyeing baths havingdifferent color dye therein, thereby dyeing each of said warps .adifferent color; simultaneously passing each of said plurality of dyedwarps through a separate sizing bath, thereby sizing each of said warps;passing said plurality of warps in predetermined spaced and parallelalignment through a timed reel drying device, thereby drying said warps;passing saidplurality of warps from said time reel drying device onto awinding bobbin, thereby winding said plurality of different coloredwarps on said winding bobbin in a predetermined spaced relation ship;arranging a predetermined number of said thus wound winding bobbins on abar thereby forming a skewered and wound bobbin; and arranging apredetermined quantity of said skewered and wound bobbins around theperiphery of a frame device; thus providing for use in said weavingoperation a group of said colored, wound warp yarns arranged inpredetermined pattern and of a number equal to said plurality times saidnumber times said quantity.
